You could have a couple of different problems here.

That's what I figured...

Have you made the comm connection live on the GPS by selecting Comm port
1 or 2? Is there a similar selection on the radio?

well; no; I've connected by nema in/out

When I did mine, I had to open the comm 1 port on the GPS to engage the
NEMA data transfer. There should be a selection on your GPS menu tabs
to enable the comm port to engage dialog with the radio.

Sorry about that wiring mixup. :)
